The Limitations of Carbon Dioxide Removal in Reversing Climate Change

Sucking carbon dioxide out of the atmosphere, known as carbon dioxide removal, cannot fully reverse the effects of climate change, according to a study published in Science Advances. The research focuses on the Hadley cell, an atmospheric circulation pattern that influences global weather. The study shows that even if carbon dioxide is successfully trapped, the consequences of pollution cannot be completely reversed on a reasonable timeline. The expansion of the Hadley cell due to greenhouse gas emissions intensifies droughts in subtropical regions, leading to food and water shortages and displacing people. To mitigate climate change, reducing emissions and transitioning to clean energy are crucial.
